# Session Log: 2026-03-16

## Summary
Investigated and fixed test station software update issue reported by Kevin at Dataforth. Station TS-8R was not getting 7BMAIN4.EXE updated after running UPDATE and rebooting.

## Root Cause Analysis
1. `T:\UPDATE.BAT` is a DEPLOY wrapper (initial station setup), not a software updater
2. NWTOC.BAT (Network-to-Computer) runs on boot to pull updates, but had two issues:
   - **Missing EXE copy**: NWTOC copied `*DATA` subfolder contents but never copied EXEs from `T:\Ate\ProdSW\` to `C:\ATE\` where they actually live on DOS machines
   - **No overwrite flag**: COPY commands lacked `/Y`, so existing files would prompt (hang on unattended boot)
3. Development had staged 7BMAIN4.EXE correctly at `Ate\ProdSW\` on AD2, but NWTOC never pulled it

## Changes Made

### NWTOC.BAT v4.0 -> v5.0
- Added `COPY /Y T:\Ate\ProdSW\*.EXE C:\ATE` (new step 2/3) to pull test executables
- Added `/Y` flag to ALL COPY commands for silent overwrite
- Removed all `*DATA` subfolder copy operations (5BDATA, 7BDATA, 8BDATA, DSCDATA, HVDATA, PWRDATA, RMSDATA, SCTDATA) -- these contain test parameter DAT files that are generated locally on stations and uploaded via CTONW; copying them back down would create cyclic overwrites
- Removed MD commands for DATA subdirectories (no longer needed)
- Renumbered steps from 4 to 3

### Deployment
- Deployed NWTOC.BAT v5.0 to AD2 `C:\Shares\test\COMMON\ProdSW\`
- Verified CR-LF line endings (DOS compatible)
- AD2-to-NAS sync will propagate within 15 minutes

## Infrastructure Checks

### AD2 Ate\ProdSW\ Contents
- 7BMAIN4.EXE: 283,456 bytes, dated 03/09/2026 (staged by development)
- 7BDATA subfolder: only DAT files (7BMAIN.DAT, TE1039DT.DAT)
- All 8 DATA subfolders contain only .DAT files (test parameters, sort tables)

### NAS Test Data Transfers (today)
- 6 stations transferred 73 files (all 7BLOG .SHT format):
  - TS-27 (28), TS-11R (15), TS-3L (11), TS-11L (9), TS-10L (5), TS-10R (5)
- No TS-8R activity (consistent with Kevin's issue)

### TestDataDB (SQLite on AD2)
- Location: C:\Shares\testdatadb\database\testdata.db (~2.8 GB, ~6.1M records)
- Import ran today at 18:23, ingested 515 records (Mar 10-13 test dates)
- No test data from Mar 14-16 (weekend, expected)
- Backup task running daily at 2:00 AM (successful)
- NAS sync last ran at 18:45

## Pending Actions
- Kevin to run DEPLOY on TS-8R tomorrow morning (deploys new NWTOC v5.0)
- After deploy + reboot, NWTOC should pull 7BMAIN4.EXE to C:\ATE
- `T:\UPDATE.BAT` (NAS root DEPLOY wrapper) flagged for deletion (not yet removed)

## Files Changed
- `projects/dataforth-dos/batch-files/NWTOC.BAT` - v4.0 -> v5.0
